After a wait the weather finally cooperated, albeit with a healthy dose of wind. Which was good in that the conditions were ideal for testing our newly made balloon containment system. BCS. There were a couple of new things this year which worked out well. First, we launched on a Friday which meant that it was a class trip as opposed to being optional. This means there were all hands on deck for the launch activities. A big plus. Secondly, we took a group of 4th graders to launch pongsats. They had a lot of fun and enjoyed the launch. Them accompanying us had an alternative motive. It was a pilot for conducting a district wide 4th grade launch. The 4th grade teacher, Kathryn Bonzo, and I are sorting out details of what worked and what didn't to make a future launch even more successful. Thirdly, we conducted a proof of concept for the BCS. Winds over 5 or 6 miles per hour made wrangling the balloon difficult. The idea is simple. A large piece of fabric to place over the balloon while being inflated and while waiting for the count down. Muslin was used to make a 5 by 7 yard fabric tarp. This material was chosen to reduce the chance of a static charge developing on the balloon. Eyelets were made at each corner and the midway points between the corners. These were tied to milk jugs filled with water. Some eyelets tore out and the jugs were not massive enough. Lessons learned. BUT the idea worked perfect. So a redesign is due for next year. The launch went perfectly and the balloon reached around 64k ft and was cut down by the timer cut down system. Future launches will have a longer time. >90 mins. Recovery happened in about 30 minutes after the module landed. Mostly due to stopping for a bathroom break.
